Mostly, I am excited that this baby will have you as an older sister, and not just because you will both need someone to call to complain about the fact that your parents are nuts. Sure, there will be times when you'll both try to kill each other either through physical brutality or embarrassment, but I know that at some point this baby is going to look up to you and think you are the coolest thing that ever walked on the planet. And while there is no way to predict the lasting dynamic of a relationship between siblings, I can only hope that you will have with this one what I have with my own, a bond so strong that it doesn't even matter that we have nothing but our parents in common. They are lifelines, people who were there, who were witnesses to everything that made me who I am, and I am the same for them in return. Is the relationship perfect? No, but we all know that we would sacrifice anything for each other, and one of the many reasons we decided to have another child was to give you the possibility of that friendship.
